hexagon.
Six sided shapes are called hexagons. If all 6 sides are the same size, then the shape is called a regular hexagon.
No because all 4 sided shapes are quadrilaterals which includes parallelograms
6 sided and 3 sided shapes respectively
No because all 4 sided shapes are called quadrilaterals which includes parallelograms
All 4 sided shapes are quadrilaterals
For a 6 sided shape to be a hexagon, it must (in addition to having 6 sides) be a polygon. To be a polygon, it must be a closed shape (no unlinked lines) and it must be convex (All angles are pointed towards the outside, rather than inwards). If it matches all of these criteria, then it is indeed a hexagon. There are many 6 sided shapes that are not hexagons, including cubes.
They are 6 sided shapes

A hexagon is a 6 sided polygon
3d shapes with six faces are called hexahedra.
